What the frame is made of?
What the frame is made of
Two builds, one standard: light enough to forget, stable enough to trust. Choose a build below to see how it's made.
AM Alloy is Klyr's aluminum-magnesium build
The name is literal — Al, Mg, the two elements the frame is made from. We chose the alloy for one reason: it holds a performance frame's lightness without the fragility that usually comes with it.
Light, without the plastic feel
Sport eyewear stays light by staying plastic. We wanted the same weight without that same feel. AM Alloy carries a performance frame's lightness, but nothing about it feels disposable. One pair moves from an early run to the rest of the day without a change of character.
Corrosion resistant, by nature
AM Alloy doesn't rust, pit, or dull under humidity or salt air. Sweat, rain, a full season of daily wear — the frame holds its line through all of it. You stop treating it like something fragile, because it isn't.
Lenses built for the pace, not just the light
Polarized lenses cut glare off wet pavement and low morning sun. An anti-slip coating keeps the frame in place through a change of pace, a turn, a full effort. Built for the space between a warm-up and a sprint — light enough to forget, secure enough to trust.
A shape borrowed from the skyline, not the trailhead
The frame's lines come from the city it's built for — angles closer to a bridge or a building than to a mountain trail. Nothing about it is decorative. Worn well, it reads as restraint, not effort.
Set against the two materials it sits between
TR Flex is Klyr's build for our TR90-based frames
The name is literal too — TR for the material family, Flex for what it does under pressure: bend without breaking, hold its shape without weighing anything down.
Four materials, one frame
A single TR90 formulation forces a trade-off between flex and structure. We split the difference — at least four TR-grade materials placed across the frame, each doing one job. The result bends where it should and holds where it shouldn't.
Weight, distributed instead of concentrated
Multi-material construction lets weight spread across the frame instead of collecting at the hinge or the temple tip. On the face, that reads as almost nothing — the kind of fit you stop noticing by the second mile.
A coating that changes what you see, not just how it looks
Every TR Flex lens carries a coating built for color enhancement — contrast lifted, glare cut, without shifting the color temperature of what's in front of you. Choose the tone that matches the light you run in.
Set against a single-material TR90 frame
Made to be worn, not just made to be light.
Every material choice here answers the same question: does it hold up to a full day, not just a photo of one.
